Activity depth profiles as area normalised distributions. Left: laterally integrated depth profiles of the activity averaged over the complete measurement frame (<A>) as obtained from the static data reconstruction (red, dashed), from the MC simulation (blue, dash-dotted), and the sum of the fitted single isotope contributions (yellow, solid). Right: depth profiles of the initial activity at the PET measurement start (A₀) as extracted from the fit of the dynamically reconstructed PET data, compared to the simulated isotope yields (black lines), for ¹⁵O (yellow), ¹¹C (red) and ¹³N (blue).
